MT – MAGNETIC PARTICLE TESTING

MT – MAGNETIC PARTICLE TESTING

Non destructive testing method of magnetic particle testing (MT) is done on ferromagnetic materials, and is widely used in aviation, automotive, energy, petrochemical and many more industry branches. Magnetic particle testing works very well with inspection of parts that must have their surface checked, or whats directly underneath it. Before the testing can begin, its vital to prepare the surface, it must be clear of all oil and grease. Ultrasonic washers are best for that, as they allow the surface of the part to be ideally clean, without any snags or splinters, so that the inspection can be accurate, without any fake indications. MT is a fast and reliable method, offering a wide choice of combinations and techniques, which can be chosen to best match the part to be tested. To perform the testing on high temperature parts that are highly hoarse, the technique of spraying the powder with a bulb syringe. For tests of sand-blasted and smooth surfaces, the black-white technique can be utilized, while the locations that require extra accuracy can be covered with UV light technique. Magnetic particle testing method allows for two ways that the part can be magnetized with, with alternating or direct current. Direct current can be used when the part is thick and large, so that the appropriate intensity of the magnetic field can be reached. Alternating current can be used when the parts have homogenous shape and same thickness everywhere.

APPLICATIONS OF MAGNETIC PARTICLE TESTING

MT method is used everywhere when the material is processed and changes shape. The industry branches that utilize MT method are  for example: aviation, automotive or founding. Magnetic particle testing are also used during inspection of welded connections and when materials are processed and machined, as well as bended, pressed or  injected.

DISADVANTAGES OF MAGNETIC PARTICLE TESTING

• can only be used for ferromagnetic materials, cannot be utilized with materials such as stainless steel, copper, aluminum or magnesium.
• problem with testing of mixed weld connections
• inproper use of the magnetic field may result in the defect not being detected
